[PATCH 6/6] btrfs: metadata_uuid: move partly logic into find_fsid_inprogress()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Su Yue <Damenly_Su@xxxxxxx>

The partly logic can be moved into find_fsid_inprogress() to
make code for fs_devices finding looks more elegant.
